I had it spoiled for me, before I even really played the game. My reaction to that was...well, I certainly didn't hate the idea. In fact, that was likely one of the reasons that I wanted to keep playing the game - although the reason I also bought the PC version, I think is due all the mods I saw on KOTORfiles, and my wish to use them. I only had the PC version of TSL at that point, and for some time, I wasn't even thinking of getting the first for it.
Anyway, my reaction to the scene the first time I saw it though, was simply "You really shouldn't have told me that."
